How can I access the data contained in Google drive tables?
I created some basic apps after reading the tutorials, but I'm unable to to see the sample data I entered.
回答1:
Option 1: Don't use Drive Tables
App Maker gives you power to connect to Cloud SQL instance, that you can access through Cloud Shell or connect with some tools like MySQL Workbench.
Pros
- Works nice if you have your own Cloud SQL instance
Cons
- This approach falls short in environments with shared Cloud SQL instances
- Cloud SQL is not free
Option 2: Export data to spreadsheet
Regardless what data backend you are using you can dump all your data to spreadsheet.
Cons
- Basically it is one-way data access (read only), unless you want to mess with importing edited data back to your deployemnt...
Option 3: Drag'n'drop way
There is an option to keep Debug page and drop on it tables/forms for models you want to look it.
Pros
- Seamless access to data directly from you development environment (browser).
Cons
- It is hard to maintain such Debug especially when you are actively working on your database structure.
- Need to think about security and hide the page from your end users.
- Need to keep dedicated datasource(s) for the debug tables/forms, that should have no filters applied (at this time there is no client-side analogue of
app.models.MyModel.newQuery()server-side API).
Option 4: Drag'n'drop way (advanced edition!)
The basic idea is to create a page with dynamic table (to view/edit data) and form (to add records). Using this highly dynamic page will eliminate shortage #1 from the option #3:
This approach has similar pros and cons as previous one plus there are some App Maker limitations that make it hard to implement (but it is doable on some extent).
